.To all whom it may concern.-

Be itknown that I, Enos F. ScnLIoHrEE, residing in the city and county` of Philadelphia', State of Pennsylvania, have invented a new and useful lImprovement in Silos, of which the iollowing is a speciiication. i

My invention consists of a novel construction of a silo, as will be hereinafter further described and claimed.

Figure 1 is a front elevation of' a portion of the silo constructed in accordance with my invention. Fig. 2 is a horizontal section thereof, taken online ,Fig.-1. Fig. 8 is a vertical section*l taken on line yfy, Fig. 1.

v Fig. 4 is a vertical section taken on line z 2,

Fig'. 1, but `with the socket of the clamping pin or bolt in section. Fig. 5 is a detail view taken online Fig. 2. Figs.l 6 and 7 are` similar detail views of a'modiiied `construe-- tion embodying my invention.` Fi 8 is another Inodied construction embo 'ng my invention, which will be understoo in connection with the following descri tion. Y

Similar letters of reference in icate corresponding parts in the iigures. `Referring to the drawings, A and B designate the door-posts of a silo of the class having 'a continuous u right doorway, C the staves next to said oor-posts, an I) doorsections for closing said doorway.

My invention Arelates to the class of silos Patent No. 653 ,967, granted to me on the 17th day or' July, `1900 and it consists of improvements thereon, one of said improvements being inthe 4construction of the door-sections D and the manner in are secured in position. In my patent before mentioned the doorosts are'each provided on their inner sides with 4upright faces converging toward the outside of the silo and the sides of the door` sections are accordingly shaped. When-the door-sections are in position, devices situated about midway between the door-posts` and the outside of the door-sections draw both of the inclined faces of' thedoor-sections against the faces vor the door-posts, and my present inventionA differs from the foregoin in this particular, in that I" preferab yp ace the means for drawing the .door-sections' out wardly at one sideoi the door-sectionsadja- Acent one of the door-posts, the instance said groove is provided with the illustrated the right-hand door-post B. This door-post -B is provided on its inner side with an upright face E, beveled outwardly and toward the doorway, and at the'adjacent side of the door-sections D is the correspondin ly-beveled face F. It is thus seen that -this end of the door-section can move Jfreely inwardly to the inside of the silo when not secured in place by the Imeans hereinafter `described and when the silage is not pressing against it. The'left-hand doorost A, however, is rovided with; an uprig t socket or groove in its inner face which receives l,the other side of the door-section D. In,Fig. 2 this groove is shown as curved in cross-section, which is a convenient construction, and aching II, of felt or other suitable materia. The inclined face E ofthe docrost B is also provided with a strip J, of fe t or othery suitable packing.

In Fig. 8 I have shown aslight modiiication in the socket or groove in the left-hand doorpost A. In this construction the groove has angular walls K and the packing-strip L is piaceri upon the inwardly-facing wall, or the wall a einst vwhich the door-section `i) is presse with the greatest force either by the tension devices hereinafter referred to or by the silage. Thus when the door-sections are placed in the position shown in Figl 2 and orce applied to the end of the door-post adja-I cent the inc 'ned faces F to move the door outwardly said inclined iaceF is pressed against the inclined face E of the door-post to make a tight joint at this point, while the other side of the door-section is forcedinto the groove Gf by reason of the inclined faces E and F.

Itis understood, ofcourse, that various de vices can be employed to force out the end of the door-sections adjacent the door-posts B Iand that my invention contemplates, broadly,

the employment of any suitable means for this pur ose, andas one embodimentthereoi I have' shown `a bolt or pin M,v securedtoone end portion ofthe door-sections, to the outer end of which is applied a hand-nut N, which engages a lug I), throughanyopening in which the-bolt M passes.- In the specific construction illustrated this bolt is provided with a semis herical head Q, 4situated within the roun ed socket l R in the. uprighty plate or IOO Y brace S, the bolt extending throughthe slotl to (prevent the door-sections from warping an at the other ends of the door-sections another one of said plates S is provided, although not having a socket. The manner in which the 'door-sections are inserted will be obvious, for after the left-hand end thereof is inserted inthe socket orgroove G the bolt, with the hand-nut loosened, is passed into the. slots U and V of the lug P, and upon reaching the socket W the hand-nut is t1 htened to draw the door-sections out with t e desired pressure, it being noted that the socket W serves to hold the bolt M in place, so that the handvnut can be easily manipulated with one handI to obtain the desired -pressure. It is understood, of course,that the slot in the lug Pcan lbe made as shown at X inl Fig. 6 or at in Another part of myinve'ntion relates to the manner in which the hoops and tie-rods are secured to the door-posts. In said Letters Patent referred tothe hoops ofthe silo do not ass entirely around the same, but merely om 'one door-post around the silo to the 'other door-post, thends ofthe hoo s being secured b nuts on the inside of t e doorposts, an in said Letters Patent I also show tie-rods extending across the doorway and between the door-posts, which are held in place by nuts on the outside of the door- -posts, these tie-rods resisting the tendency of the-door-posts to separate. These tie-rods are also rovided on the inside of the doorposts wit nuts, which are mainly useful in the setting up of the silo, as the doors are usually made complete at the factory, so Vthat these inside nuts aid in holding them in pos1 tion. In the present construction I employ similar hoops A and the tie-rods B", their ends passing through the door-posts A.and B and being secured 1n position by the nuts C', D', E', and F', the plates Gf andH situated between these nuts and the outer'and inner sides of the door-posts.

. My present -inventiondiffers from that shown m sald patent, in that the doorosts in the present mstance are situated ra ially with respect to the silo--that is to say, a -line passin vat a right angle to the outer face of these oor-posts or parallel to its sides would `be approximeatly a radius ofthe silo. In

this way I can reduce the thickness'of theV door-posts from the inside to the outside,y and thereby use lighter material in the construc- 'tionof the same, because I am then enabled to extend the hoops nearer the outer faces 'of the door-posts and also to place the hoops that the strain u on the door-posts is more and tie-rods directly o ne above the other, so a evenly distribute ,since the outer ends of the 79 tie-rods and the ends ofthe oops conform to the lcurvature of the remainmgyportion of the y hoops, as will be seen upon reference to Fig. 2. In silos, however, of this class a ladder extends between the door-posts, and I em- 7,5 ploy the tie-rods to form this ladd'er, and to accomplish this the central portion ofthe tierods are bent outwardly, as shown in J, tof afford sufficient space between said tie-rods and the door-sections and give the de'sired 8o foothold, it being noted that .as the ends of the tie-rods extend at an angle to 'the curved portion J the said curved portion of the tierods will be prevented from being depressed or turned by the weight of the person standing thereon, and especially when the nuts C and Dy are tightened. It will also be seen that the ends of the hoops A `and of the tierods B are tangential to the curve of the silowallsv and substantially parallel with each go tance both as maintaining the integrity of the joints between the door-posts and adjacent staves as well as between the door-posts and the door.

Having thus described my invention ,what I claim as new, and desire to secure by Letters Patent, isa l 1. A silo having a doorway provided at one side with a socket and at its other side. witha beveled abutting'face, a door having a v beveled .abutting face at one side thereof to contact Awith the abutting faceof the doorway, whereby the inner faces of said door and said doorway may be brou ht into substantial alinement the other en Aof said door being adapted to enter said socket, and means for drawing outwardly the side ofv said door adjacent the said beveled abutting face.

2.'A silo having a doorway provided vat IOO one side with a socket and at its other side with a beveled abutting face, a door'having a beveled abutting face at one side thereof to contact withthe abutting face of the doorway, whereby the inner faces of said door and said doorway may be brought into substantial alinement the other side of said door beingadap'ted to enter said socket, and'coacting` means situated upon the side portion of the door adjacent said abutting face and upon the adjacent door-post for drawing said .door outwardly and lholding said abutting faces in contact under pressure.

- 3. -Asilo having a doorway, a door fitting I saiddoorwa the engagement 'between said doorway an 'door atone side thereof servmg to prevent the ldoor from moving either out wardly orfjinwardly, the engagement between said door and doorway at the other side there of serving to revent the door from moving outwardly on y, and means for drawing said door outwardly consisting ot' a movable bolt Carried by the door and provided with anut and a slotted lug mounted upon the doorost. f p 4. A silo having,r a doorway, a door fitting said doorway, the engagement between said 'doorway and door at one eide thereof serving to prevent the door `from moving outwardly or inwardly, the engagement between said door and doorway at the other side thereof serving to prevent the door fromy moving outwardly only, and means for drawing said door outwardly consisting of a movable bolt carried b the door and provided with a nut and a s otted lug mounted upon the door-post, the outer end of said slot be .ing situated at the bottom ofthe lug and said said door and doorway at the other side thereof serving to prevent the door from moving outwardly only, said door being substantially lueh with the doorway at both Sides, a 1novl able bolt secured. to the end portion of the door`- incapable of moving outwardly only, said bolt being1 provided with a nut, and a lug upon the door-post adapted to be engaged by said nut.
